Physical therapists employ a variety of modalities to control the pain often associated with many orthopedic injuries. Two commonly used modalities include ultrasound and electrical stimulation.
What Is Ultrasound Stimulation?
Ultrasound utilizes high-frequency sound waves to create a deep heating effect through cellular oscillation and vibration. This movement produces friction, which in turn causes the temperature of the target tissue to increase. This warming effect can promote relaxation, increase tissue length and alter pain transmission.
Another method of pain control commonly used in the physical therapy setting is electrical stimulation. Electrical stimulation produces a gentle tingling sensation over the surface of the skin.This tingling sensation is transmitted along nerve fibers that are separate from those carrying pain.
Ultrasound and Electrical Simulation Theories:
According to one theory, as these competing lines of information travel into the spinal cord and brain, the pain messages are blocked or gated. Only the tingling sensation reaches the brain, reducing and sometimes eliminating pain temporarily. Application of these treatments before or after exercise can often make the early stages of rehabilitation more tolerable, allowing patients to return to their previous activity level more quickly.
